Specifically, can't build the "Space Platform Starter Pack", or anything else on the Space Tab, except for the Rocket. If I cheat in the "Space Platform Starter Pack", the Rocket doesn't register it as being a "Space Platform Starter Pack". If I uninstall this mod, I can launch rockets like normal, and craft all the items in the space tab.

Have fixed the issue. Apparently the code that was used previously wasn't compatible with space-age so it kind of just deleted them from existence.

So apperently i did not fix the issue with space platforms before, however i did find the issue and fix it for good this time.
